Breakfast Session: Energy Recovery Wheels
Wednesday, October 6
Laboratories typically require high ventilation rates
that cause significant heating and cooling energy use. Energy recovery
systems can substantially reduce heating and cooling energy associated
with conditioning laboratory ventilation air, thus saving energy
One emerging technology for achieving energy recovery in laboratories
is the so-called "heat wheel" or rotary heat exchanger.
A basic heat wheel recovers sensible-only energy between the lab's
exhaust air and the incoming outside air. Advanced versions of the
heat wheel, called enthalpy wheels, transfer both sensible and latent
energy. Both enthalpy wheels and total energy wheels, sometimes
referred to as desiccant wheels, are currently available.
This breakfast session explored issues relating to this exciting
- Emerging issues related to using energy recovery wheels.
- Experiences with the design and engineering of these systems.
- Current status of the technology, as well as limitations and
